Answer:

A)   Pulsar

Explanation:

Pulsars are collapsed cores of stars usually supergiant stars

this happens when a supernova leaves behind the star core that has no outer protection layer of high gravity so the core collapses in on itself to create a very high magnitude star and also has trillions more mass.

Answer:

A

Explanation:

It is formed after the star has ended its star cycle into a supernova. The star collapsed into a neutron star that is smaller than the progenitor star but has inherited angular momentum. IT, therefore, spins faster emitting electromagnetic radiation that seems to pulsate.

For the quantum number lower case L = 0, how many possible values are there for the quantum number m subscrip l?
hram777 [196]
Quantum number L, angular quantum number, describes the shape of the orbitals. Reliable sources show that the quantum number l = 0 will give an orbital of spherical shape, polar if l = 1, and cloverleaf if l = 2.

The third quantum number is m which is is used to denote the magnetic quantum number. This describes the orientation of a certain orbital in shape. This quantum number can take the values of -l to l. Thus, the only value for m in this case is 0. m = 0.  

Quantum numbers are used to describe the position of the electrons in the orbitals.
